Played this game twice through and i am interested as to what other endings people got, please share

The game never starts. All I see is the game icon and when I went to fullscreen it froze with a white screen. I'm using it on a Macbook Pro with a NVIDIA GeForce 9400M

every time I pick up something when I say no nothing happens and the only button will work is the yes button. I hit escape quite a bit into the game and couldn't say no I don't want to quit as it doesnt seem to save the game but I couldn't and only the yes button would work again. How do I resolve it as it seems I will need to say no to get some achievements!...

I keep running into an issue where the game will freeze at the dialogue and I can't continue the game in the room where it has a rusty ladder stuck in a pool of putrid water. Have to reboot the game everytime I am near the room, and it's stopping progression. Anyone knows what's the issue?...

ive tried re-installing it and restarting my computer, this game is messed, the buttons don't show, once i got into the game my character is invisible. please help.
